Temporary hair loss concealers normally come in one of three forms: cream, compact powders or colored sprays.
The goal of each is to minimize the contrast between scalp and hair.
hair loss concealers work in a similar way to facial concealer. They are sold as densely packed colored powder or sometimes creams which are applied directly to the bald spot. The concealer temporarily dyes the hairless areas and it clings to the existing hair so that is looks thicker.
Modern concealers are much better than those of the past, especially in terms of color matching and staying on in the rain!
You can use them every day without causing any further deterioration in your existing hair.
